Assessment of Striga gesnerioides (Willd.) Resistance and Genetic Characterization of Forty-Six Cowpea (Vigna unguiculata (L.) Walp.) Genotypes in Ghana

Figure 2

Phylogenetic relationship among 46 cowpea genotypes. A dendrogram was generated using sixteen informative SSR markers and sequential clustering algorithm (UPGMA) based on genetic similarity. UCC −E = UCC − Early; UCC − W = UCC − White; APAGB = Apagbaala; SARCL = SARC − LO2; IT97K = IT97K − 499-35;  = Striga-resistant; and ■ = Striga-susceptible.
